Wind Resistant Design and Response Control of Tall Building
This paper presents an overall view of the wind resistant design and response control of the tall buildings in Japan, the Crystal Tower in Osaka and the Landmark Tower in Yokohama. The...
The Engineer's Role in Reducing Curtainwall Failures
For a variety of reasons, engineers have abdicated responsibility for curtainwall design. Failures of curtainwall components are very common, leading to expensive repairs and even complete...
Things That Fall?Lessons from Some Construction Accidents and Structural Failures
The causes and results of several construction accidents are reviewed. The lessons to be learned from such a summary are that all too often the simplest oversight leads to catastrophic...
Tuned Mass Damper in Tall Building Design
Viscoelastic dN and tuned mass dampers are often used by tall building designers to control wind-induced building vibrations resulting from such phenomena as vortex shedding, galloping,...
Tuned Mass Dampers for Towers and Buildings
Tuned mass dampers (TMD's) are used to reduce the response of tall slender structures to resonant wind-induced oscillations. This paper reviews the authors' experience with the design...
Passive Energy Dissipation Systems for Earthquake-Resistant Design
Passive energy dissipation devices, also known as supplemental damping devices, have been proposed as a means by which the earthquake resistance of a building can be substantially enhanced,...
Evaluation of Seismic Isolation Schemes for a Historic Building
The U.S. Court of Appeals Ninth District building originally completed in 1905 with an expansion in 1933, suffered damage during the 1989 Loma Prieta earthquake. The building is currently...
Wind Hazards Reduction Program
The 1990's mark the International Decade for Natural Disaster Reduction. In this context, the Wind Effects Committee of the Structural Division strongly endorses the establishment of a...
Diagnosing Lateral Strength of Existing Concrete or Masonry Buildings
A research prospectus is presented for improving present methods of structural evaluation for concrete and masonry buildings. Specifically, the proposed research plan is limited to strength...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...
Seismic Assessment and Renovation Study for Highway Bridges
This paper is concerned with hazards mitigation on highway bridges due to earthquake ground motions. Damage to transportation systems may occur if the acting faults of May-Shan and Tsu-Kou...
Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...
Correction Factor Method for Building Analysis Under Sequential Dead Loads
The effect of the sequential application of dead load due to the sequential nature of construction is an important factor to be considered in the multistory frame analysis. One of the...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
Dynamic Inelastic Analysis of Tall Buildings
Members with undesirably early formed plastic hinges as well as excessive conservatism introduced in the preliminary design of tall buildings can be identified by the behavior state study...
